Trigonometry Ratios of Specified Angles:for SSC and Competitive exams
Trigonometry Ratios of Specified Angles:
- Sin(A+B) = SinA.CosB + CosA.SinB
- Sin(A-B) = SinA.CosB - CosA.SinB
- Cos(A+B) = CosA.CosB - SinA.SinB
- Cos(A-B) = CosA.CosB + SinA.SinB
- 2 SinA.CosB = Sin (A+B) + Sin (A-B)
- 2 CosA.SinB = Sin (A+B) - Sin (A-B)
- 2 SinA.SinB = Cos (A+B) - Cos (A-B)
- 2 CosA.CosB = Cos (A+B) + Cos (A-B)
- Sin A + Sin B = 2 Sin (A+B)/2.Cos (A-B)/2
- Sin A - Sin B = 2 Sin (A-B)/2.Cos (A+B)/2
- Cos A + Cos B = 2 Cos (A+B)/2.Cos(A-B)/2
- Cos A - Cos B = 2 Sin (A+B)/2.Sin (A-B)/2
- Sin2A - Sin2B = Sin(A+B) - Sin(A-B)
- Cos2A- Cos2B = Cos(A+B) - Cos(A-B)
